The features of the crystal structure of the layered series hydrates of uridine-5'-monophosphate salts (UMPNa _x ·yH₂O).

ABSTRACT: Almost all reported salts of nucleotides crystallized from solutions are in the form of hydrate. Layered hydrates often occur in crystals with more than five water molecules per host molecule. In the present report, five single-crystal structures of uridine-5'-monophosphate (UMP) series hydrates of acid or salts (UMPNa _x ·yH₂O, x = 0-2) were determined and analysed. It was found that all crystal hydrates were orthorhombic with a C222₁ space group but with mere variation in the plane angle of adjacent bases and the distance between phosphate arms. The packing arrangements of UMPNa _x ·yH₂O hydrates present typical layered sandwich structures and show that the UMP molecular layers alternate with w
